    gen set exiter/field regulator

    I have an American Marc/Kato gen set with a bad exiter/regulator. Unit is 35 years old, looking to replace it with solid state circuitry. Does anyone have generic schematics for this? Field voltage needed is 50-70 volts DC at approx. 5A to generate 120/208 3 phase. Static field resistance is...
